The petrol economy for auto is **** if you drive it like a car. If you glide it a lot, you may get something better.
I got my brother one for 635k in lahore about 6 months ago in pretty decent condition. Later he installed CNG in it, and the ABS kinda doesn't work when its on CNG. In fact the brake doesn't work bec the rpm drops. It does give about 130-140km in around 550 rupees of gas both locally and on highway.
Its totally sluggish - the slowest car i have come across when it comes to acceleration. But it gradually accelerates to 130kmph and is far stable at those speeds than any other 1000 cc local car i have experienced.
